I think the concern, perhaps with little merit, is that the PC resident
data may be accessed by some other PC process, without knowledge. This
is likely due to all the horror stories about Windows being subverted
and data mined with no knowledge of the company which owned the data.
Now, with proper setup, this should not be a real concern. If the PC
running your software is secured inside the data center, and if it
either has no LAN access to anything other than the mainframe, then I
can see using it. Especially, perhaps, for things which do not need the
high security. The plus of the other DASD you mentioned is that it is
not IP connected. It is connected via Fiber directly to the mainframe.
That means that there is absolutely NO way for "somebody" to put a
"sniffer" on the LAN and capture data in transit (we do all use TLS for
our TN3270 sessions, right?). Of course, if this is a real concern, then
the LAN could be set up so that the PC running MFNetDisk was on a
separate VLAN or even a physically separate LAN segment that doesn't
connect to anything else.

Another part of the fear may be that mainframe information is being
accessed without any mainframe auditing. I assume that any data which is
transferred to another system has already been audited on the Mainframe
as being "OK" to send. I also assume that the data, once on the
receiving system, is properly secured and access audited if necessary.

Lastly, suppose that all the above is properly vetted and secured. There
needs to be some way for users of your API to know when the DB2
structure has been changed. For instance, suppose that a table is
deleted, or just a column deleted. There needs to be some way for the
people who maintain the PC application to know this and update their
application. I know that this is a tremendous problem here. Because
believe it or not, the PC application people scream if anything changes
and they have to modify their code to adjust. This is not a problem with
your product, but it is a problem if we on the mainframe side have been
"bitten" by it. We have actually had to defer changes due to the PC
processes not being updatable in a timely manner. So much for the PC
having a faster development cycle. Again, at least around here.
